Manual

1. Safety Labeling and Signal Words
Danger, Warning and Caution
The signal words DANGER, WARNING and CAUTION are used
to identify levels of hazard seriousness. The signal word DAN-
GER is only used on product labels to signify an immediate haz-
ard. The signal words WARNING and CAUTION will be used on
product labels and throughout this manual and other manuals that
may apply to the product.
2. Safe Installation Requirements
Installation or repairs made by unqualified persons can result
in hazards to you and others. Installation MUST conform with
local building codes or, in the absence of local codes, with the
National Electrical Code NFPA70-1990 or current edition.
The information contained in this manual is intended for use
by a qualified service technician familiar with safety proce-
dures and equipped with the proper tools and test instru-
ments.
Failure to carefully read and follow all instructions in this
manual can result in unit malfunction, property damage, per-
sonal injury and/or death.
• Seal supply and return air ducts.
• Check to see that filters are installed correctly and are the
proper type and size.
NOTE: It is the personal responsibility and obligation of the cus-
tomer to contact a qualified installer to ensure that the installation
is adequate and conforms to governing codes and ordinances.

CAUTION
Do NOT operate unit in a corrosive atmosphere containing
chlorine, fluorine, or any other corrosive chemicals.
3. Locating & Installing The Unit
The unit is designed for outdoor installation only. Place the unit on
a platform at ground level. The unit may be installed on a concrete
slab of 48" (1219mm) x 48" (1219mm) dimensions. Cement
blocks on a 3" sand footing will also work. The slab or blocks
SHOULD NOT be in contact with any part of the structure. Check
local codes covering zoning, noise, platforms, etc..
If practical avoid locating next to fresh air intakes, vent or bed-
room windows. Noise may carry into the openings and disturb
people inside.
Avoid installations under roof overhangs without guttering. Water
draining from the roof onto the unit could produce excessive
noise, and may cause ice to build up on coil or fan.
Placement of the unit should be in a well drained area or the unit
MUST be supported high enough so runoff will not enter the unit.
Do not locate unit where heat, lint or exhaust fumes wil! be dis-
charged on unit (as from dryer vents.)
Clearances
Minimum clearances, as specified in FIGURE 1, MUST be main-
tained from adjacent structures to provide adequate air circula-
tion and room for service personnel.
While minimum clearances are acceptable for safety reasons,
they may not allow adequate air circulation around the unit for
proper operation. Whenever possible, it is desirable to allow addi-
tional clearance, especially around the condenser inlet and dis-
charge openings.
Do NOT install the unit in a recessed or confined area that will per-
mit discharged air from the condenser to recirculate to the con-
denser inlet.
